Of course, Weekly Shonen Jump has always had more than gag series and straightforward adventures. It's been home to more than a few romance stories over the years. It's just debatable how well they have aged (or even if they were any good to begin with).
KIMAGURE ORANGE ROAD (Kimagure Orenji Rodo), by Izumi Matsumoto. First published in 1984 and first published in North America in 2014.
PLOT:
Kyosuke was just wandering around the park in his new hometown when he met with Madoka. He was instantly smitten with her, but has a hard time believing that the same sweet girl he met in the park could be a standoffish deliquent at school. That doesn't stop him from crushing hard on her, something that only becomes more complicated when he ends up stumbling into a relationship with Madoka's spunky best friend Hikaru. Can Kyosuke sort out his relationship problems and keep his family's psychic powers a secret?
